Today’s stupid, broken IOT device: the Cosori Smart Air Fryer.

A heap-based buffer overflow vulnerability exists in the configuration server functionality of the Cosori Smart 5.8-Quart Air Fryer CS158-AF 1.1.0. A specially crafted JSON object can lead to remote code execution. An attacker can send a malicious packet to trigger this vulnerability.

Science Sunday!

It seems like it has been a while since I’ve done anything computer or computer history related. How about something from General Electric? Specifically the “Heavy Military Electronics Department”?

“Systems That Look Ahead”, a 1960s promo video on the virtues of computer information processing.

Honestly, I’m just fascinated by the idea of the “Heavy Military Electronics Department”. Was there a “Light Military Electronics Department”?

Bonus #1: They call economics the “dismal science”, right? Actually, this sits kind of at the interesection.

“Economics of Nuclear Reactor”, with our old friend Illinois EnergyProf.

Bonus #2: Periscope Films has put up some more educational videos from Shell Oil. This is actually one that they posted a while back from the 1970s that’s in color: “How an Airplane Flies: Part 1, Weight and Lift” and “Part 2: Thrust and Drag”.

Phone Phriday!

Okay. I’m not sure I’m going to actually make that a thing.

But for today, how about some more vintage fun from the AT&T Tech Channel?

“The Astonishing, Unfailing Bell System” from 1967.

This film focuses on the integrity and reliability of the entire Bell System network, circa 1967, to handle large quantities of not just voice information and phone calls, but also data, text via teletype, pictures, and television signals. It’s a series of small case studies in how the national system fit together to deliver all kinds of information, from tracking train cars to transmitting live television broadcasts.

Bonus #1: I’m sure some of my readers – the younger ones – may be asking the question “What is this ‘Bell System’ you keep going on about?”

“What is the Bell System?” from 1976.

Bonus #2: If you haven’t had enough nostalgia already, this might do it for you.

“AMPS: Coming Of Age” from 1979. This is about the early mobile phone network:

The Chicago test cellular network was built in 1977 by the Bell System and had tests during 1978; this film was made in 1979 after a year with 1,300 customers using the system.

This is the only one of the three with an intro, and the only one where I’ve set it to start after the intro.

Science Sunday!

I’ve got another NASA film lined up today, but this isn’t space science.

“Flight to Tomorrow” is a 1967 film about NASA’s supersonic aircraft research, including the SST, hypersonic transports, and noise abatement.

Bonus #1: I thought it might be interesting to post this: “The M2-F2 Crash” from the Dark Footage folks.

Why? Well, some of you may recognize the M2-F2. Some more of you may recognize some of the footage in this documentary. Otherwise, stay to the end, when all will be revealed.

Bonus #2 and #3: The history of the M2-F2 and the NASA lifting bodies led me to this.

“Today, Tomorrow and Titan III”, part one of “Man In Space”. I know I’m sort of fudging here, but I really do view lifting bodies and supersonic/hypersonic transport as being a different category of science than the manned space missions.

Part 2: This also covers Bill Dana and the X-15.

Bonus #4: Just one more, because it is short. The Martin Marietta X-24B lifting body.

Science Sunday!

I’m thinking a little bit of space science today.

First up, a nice little historical video direct from NASA about the Mercury Control Center.

That covers Mercury. How about Gemini?

“The 12 Gemini”.

Apollo? Well, would you settle for a vintage Rocketdyne promo video on “Large Liquid Propellant Rocket Engines”, like the F1 engine used in the Saturn V?

Last one, and it is a long one. But today is Sunday. “Engineering Space: The Mighty Saturn V”.

Happy Easter!

404 – body not found.

Today through Sunday are going to be busy, so there’s probably going to be a strong dose of random.

I haven’t done anything with food in a while, so how about a seasonally appropriate recipe?

“Erich Shows us How to Make Hasenpfeffer”.

Another version from AlmazanKitchen:

Now I know why I don’t post more food videos: I’m hungry. So let’s switch gears.

Here’s another historical video from the AT&T Tech Channel: “The Thinking Machines”.

This film, meant to be shown to high school students, uses the device of “computer vs. human” in the comparing of their thinking abilities, told through animation and live action. The animation is Jetsonian, the concepts a little ahead of their time.

As I generally do, I’ve set this up to skip the intro.

One of the reasons this past weekend was so busy is that I got up brutally early Saturday morning and drove out to the KR Training facility (KR Training, official firearms trainer for WCD) to attend a “Stop the Bleed” class taught by Levi Nathan.

I know there are many gun bloggers who feel like: if you carry a gun, you should carry a tourniquet, too. I haven’t been doing that because:

  • I didn’t have the training.
  • I have heard a lot of horror stories about low quality knockoff tourniquets made of Chinesium. I wanted to make sure I knew what suppliers were reliable, and how to tell a counterfeit tourniquet from a real one, before I started spending money on putting together an emergency kit (or what people in the biz call an IFAK).
  • I also wanted to know what I should – and should not – put in my emergency kit.

Summarizing: I got exactly what I wanted out of Mr. Nathan and the course, and I heartily endorse this event and/or product.

And even though this was at KR Training, this isn’t just a gun thing, for all my foreign readers. People hurt themselves badly and suffer life threatening bleeding in all kinds of ways: car accidents, construction accidents, kitchen accidents…

I also heartily endorse the idea of taking an official “Stop the Bleed” course from someone, anyone. You’ll get hands-on practice with stuff, and hands-on practice is good.

That being said, today’s videos are all StB related. Some of this is for my own personal bookmarks, and some of this is for the benefit of my loyal readers who want the knowledge, but may not yet be able to step out and take a StB course.

Remember: Have gloves. Wear gloves. Nitrile is recommended.

This is a compressed (slightly over 15 minutes) version of the “Stop the Bleed” presentation.

Here’s a longer version (a little over an hour) with demos.

Again, these are not substitutes for taking a for real actual course from someone who knows what they are doing. But I know a lot of people still don’t feel like it is safe to go out and mingle in public, so this is better than a poke in the neck with a sharp stick.

And from North American Rescue, makers of the Combat Application Tourniquet (C-A-T), here’s how to apply one:

NAR has a content rich YouTube channel. Here’s another video on the use of the emergency trauma dressing.

And from ITS Tactical, here’s a video on using the Israeli bandage:

Finally, by way of SkinnyMedic, “How to use your IFAK”.

Note that some of these channels talk about stuff other than trauma dressing, gauze (for packing) and the C-A-T: for example, chest seals.

The advice we got in class for using chest seals (and even more emphatically, chest decompression needles) was: don’t. Chest seals seem to show up in a lot of pre-packaged IFAKs, but as Mr. Nathan put it, this is not within your scope having taken just a “Stop the Bleed” course. This is the kind of thing that EMTs with higher level certifications do, not random hobos such as myself.

Also, if you get someone else’s blood on you: tell the responding medical people. We all know about HIPAA, right? Well, there’s a limited exception in the law: if you get someone’s blood on you, and it is documented, and it turns out that person has a blood-borne pathogen, you have a right to be informed of that as long as it is documented. You don’t have a right to know how and where they got it, just that they had it.

Now all I need to do is get my (stuff) together. I’m actually kind of surprised at how many of the companies selling IFAK pouches don’t make them in red. Condor is the only one I’ve found: 5.11 doesn’t, for sure.

The pouch should be the cheapest part of your kit, as long as it holds everything in place. But in a high stress emergency situation, I’m personally thinking “red = first aid”, and I want to be able to tell people “grab the red pouch”, not “grab the black pouch, no, the small black pouch, no, the other small black pouch, no, that’s the dark purple one, grab the black one…” Know what I mean, Vern?

Science Sunday!

I’ve got a few things for you today. First up: “ABCs of Radiation” with “Illinois EnergyProf“, which gives a nice explanation of alpha, beta, and gamma radiation for the uninitiated. You know, for kids.

Bonus #1: Some kind person appears to have uploaded all of Jonathan Miller‘s “The Body In Question” series to the ‘Tube. I wanted to see this when it was first run on PBS in America, but for some reason I don’t recall at the moment was unable to.

Here’s episode #1:

Here’s the playlist.

Bonus #2: Have you ever asked yourself, “How do atomic clocks work?”

Here’s how the The NIST-F2 Atomic Clock works:

And here’s a more general introduction:

Bonus #3: which, of course, was nicely set up by the previous videos. This guy’s voice is right on the ragged edge of annoying for me (he reminds me of Inspector Clouseau), but I thought the content was worthwhile for HP fans: the HP 5061A Cesium Clock.

Here’s a two-parter for you. From 1966, and an old show for children called “Discovery“.

“The World Beneath the Sea”, part 1. This is mostly about marine animal life.

“The World Beneath the Sea”, part 2. This concentrates a lot on things like scuba diving, minisubs, and SeaLab II, which would have been right up my alley when I was a child (and is still right up my alley today).

I was talking with my brother about calculator watches recently, which reminded me of this video from Techmoan: “Hewlett Packard HP-01 1977’s Smartest Watch”.

As a HP geek, I would kind of like to have one of these: however, examples in good condition are expensive.

Bonus #1: I also thought it might be interesting to do some startup videos. Not tech startups, but starting up things. For example, an Airbus A320:

Bonus #2: Or a railroad locomotive.

Bonus #3: Or a DC-3.

Bonus #4: Or a tractor, “with a 12 guage shotgun shell”. I believe this gives new meaning to the term “shotgun start“.

You see the signs, but you can’t read…

Sunday, March 21st, 2021

Sometimes, the warning signs are lit up with neon and searchlights, and people still miss them.

A married pair of San Francisco entrepreneurs were indicted Thursday on multiple federal charges, the latest twist in the saga of a once trendy, now bankrupt fecal matter-testing startup.
Zachary Schulz Apte and Jessica Sunshine Richman, co-founders of defunct microbiome testing company uBiome, are accused of bilking their investors and health insurance providers, federal prosecutors said. They were indicted Thursday on multiple federal charges, including conspiracy to commit securities fraud, conspiracy to commit health care fraud and money laundering.

Now, I’m just a poor dumb white boy from Hampden, but I feel like there’s at least two big warning signs that were missed here.

1.

San Francisco-based uBiome was founded in 2012, and kicked off the company in an unusual way for a biotech startup: via a Kickstarter campaign. Its offering was an at-home test to sequence the DNA of its customers gut microbiome, which could then in turn purportedly be used to improve health.

I’m an absolute believer that you should avoid – indeed, run away from – any crowd funding campaign that is medical or health care related.

2.

In 2018, Richman was even named an “innovator” winner in Goop’s “The Greater goop Awards” and at its peak, uBiome was valued at $600 million.

Goop? Seriously? No s–t.. Again: anything that’s recieved an award from Goop, is promoted on Goop, or has any involvement with Goop: run like hell in the other direction.
